Q:多个ISDN bri接口的是否可以进行mp捆绑?

A:可以支持。

做法很简单,正常拨号配置(老命令行):配置dialer口,在ISDN物理接口下配置dialer rotory-group,再在所有接口下配置ppp multilink就行了。

需要注意的是对版本有要求,以前1.2、1.3的老版本不支持,但1.6的版本肯定可以。
另外就是如果拨号上网的话,ISP需要支持4个B道的捆绑。

 

,实现在ISDN线路上既进行mp捆绑,又进行回呼。我们做的配置如下,可以实现4个bri捆绑上pri
验证已经通过:
但我们只能使用ISDN主叫号码回呼方式才能实现该需求。
利用ppp的用户名验证或者根据回呼号码两种方式进行
回呼都不能实现mp捆绑。
